Soon (スーン, Sūn?) is a character in Bakugan: Mechtanium Surge and she was part of Team Sellon but is now an unofficial member of Battle Brawlers. She is a Haos Brawler and her Guardian Bakugan is Spidaro.
In Fall From Grace, it is shown that she does not favor Sellon picking Chris in the tag battle against Dan and Shun - since they are losing. She later comments on Sellon's "victory" by getting the crowd's favor in the end.
In A Royale Pain, she partners up with Krowll in the Battle Royale competition. She teams up with Robin and Hyper Pulsor, while she uses Slicerix against Shun and the other brawlers. Before they can win, though, Taylean creates Silent Strike who defeats both of them.
In Mind Search, she, along with Chris, participate in the Capture the Flag challenge but lose in the battle against Shun.
In True Colours, she and Chris survived the Chaos Bakugans' second raid. They found out that Sellon was working for Mag Mel and was just using them.
In Behind the Mask, she lost her confidence and her reason to survive. She even doubts the brawlers ability to win the battle after she was saved. However, Shun gave her and Chris the confidence to fight, she would then help defeat the remaining chaos Bakugan to protect Dan.
In Dark Moon, Soon help battle the chaos Bakugan while the other brawlers focused on defeating the Mechtogan and Mechtogan Titans. Soon and Chris has apparently made Shun their leader, replacing Sellon.
In The Final Takedown, while fighting against Mechtogan Titans, she and Chris heard Sellon's voice and run towards it. Later, they reunite with the Brawlers and Team Anubias after Dan defeats Mag Mel.
